Storage Array
NOTICE:
Removing or manipulating an access virtual disk can cause a loss of
management access. If you remove an access virtual disk mapping from an
in-band-managed storage array, MD Storage Manager can no longer access the
storage array. Do not modify the access virtual disk either in the operating system or
with MD Storage Manager.
Out-of-Band and In-Band Management
You can manage a storage array in two ways:
•
Out-of-band management
•
In-band management
For out-of-band management, data is separate from commands and events.
Data travels through the host-to-controller interface, while commands and
events travel through the management port Ethernet cables.
When you use out-of-band management, you must set the network
configuration for each RAID controller module’s management Ethernet port,
including its Internet Protocol (IP) address, subnetwork mask (subnet mask),
and gateway. If you are using a Dynamic Host Configuration Protocol
(DHCP) server, you can enable automatic network configuration, but if you
are not using a DHCP
server, you must enter the network configuration
manually.
NOTE:
RAID controller module network configurations can be assigned using a
DHCP server (the default setting). However, if a DHCP server is not available and the
10-second selection period times out, the RAID controller modules use the
192.168.128.101 static IP address for controller 0. For controller 1, the RAID
controller modules use the 192.168.128.102 static IP address.
For in-band management, commands, events, and data travel through the
host-to-controller interface. Unlike out-of-band management, commands and
events are mixed with data.
For detailed information on setting up in-band and out-of-band management
see the
Installation Guide.
NOTE:
In-band management is not supported on systems running the Red Hat
®
Enterprise Linux
®
3 operating system.
